[JIRA] (HHH-16494) Right or full joining on single tablepolymorphic entities gives incorrect results

by Jan Schatteman (JIRA)

Jan Schatteman ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYTM5MmM2NWIz... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16494?atlOrigin=eyJpIjoiYTM5Mm... ) HHH-16494 ( https://hibernate.atlassian.net/browse/HHH-16494?atlOrigin=eyJpIjoiYTM5Mm... ) Right or full joining on single tablepolymorphic entities gives incorrect results ( https://hibernate.atlassian.net/browse/HHH-16494?atlOrigin=eyJpIjoiYTM5Mm... ) Issue Type: Bug Affects Versions: 6.2.1 Assignee: Unassigned Components: hibernate-core Created: 19/Apr/2023 08:20 AM Priority: Major Reporter: Jan Schatteman ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) See JoinWithSingleTableInheritanceTest. testRightJoinOnSingleTableInheritance `and JoinWithSingleTableInheritanceTest.testFullJoinOnSingleTableInheritance for examples of this. The problem is that the {{<tablealias>.dtype=xxx}}part gets added to the on clause, and this leads to incorrect results. Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) stated that that condition should be pushed down into the tablereference, e.g `ight join (select * from child_tbl where disc = 'child_a') c on ...` ( https://hibernate.atlassian.net/browse/HHH-16494#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16494#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!

[JIRA] (HHH-16492) Hibernate 6 does not auto flush when calling Query.stream()

by Jean-Francois Fournier (JIRA)

Jean-Francois Fournier ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16492 ( https://hibernate.atlassian.net/browse/HHH-16492?atlOrigin=eyJpIjoiZDc0OT... ) Re: Hibernate 6 does not auto flush when calling Query.stream() ( https://hibernate.atlassian.net/browse/HHH-16492?atlOrigin=eyJpIjoiZDc0OT... ) Hello, If you look at the documentation here : https://docs.jboss.org/hibernate/orm/6.1/userguide/html_single/Hibernate_... it says that it will flush the session if you use the entityManager to create the query. If you use the session to create the query it will not flush. In your test you use the session instead of the entityManager to create the query. That’s why it’s not flushing in hibernate 5. If you use the entityManager it would flush. Thank you Extracted from the link above : When executing a native SQL query, a flush is always triggered when using the EntityManager API. Example 414. Automatic flushing on native SQL using EntityManager assertTrue(((Number) entityManager .createNativeQuery("select count(*) from Person") .getSingleResult()).intValue() == 0); Person person = new Person("John Doe"); entityManager.persist(person); assertTrue(((Number) entityManager .createNativeQuery("select count(*) from Person") .getSingleResult()).intValue() == 1); If you bootstrap Hibernate natively, and not through Jakarta Persistence, by default, the Session API will trigger a flush automatically when executing a native query. Example 415. Automatic flushing on native SQL using Session assertTrue(((Number) session .createNativeQuery("select count(*) from Person") .getSingleResult()).intValue() == 0); Person person = new Person("John Doe"); session.persist(person); assertTrue(((Number) session .createNativeQuery("select count(*) from Person") .uniqueResult()).intValue() == 0); To flush the Session , the query must use a synchronization: Example 416. Automatic flushing on native SQL with Session synchronization assertTrue(((Number) entityManager .createNativeQuery("select count(*) from Person") .getSingleResult()).intValue() == 0); Person person = new Person("John Doe"); entityManager.persist(person); Session session = entityManager.unwrap(Session.class); assertTrue(((Number) session .createNativeQuery("select count(*) from Person") .addSynchronizedEntityClass(Person.class) .uniqueResult()).intValue() == 1); ( https://hibernate.atlassian.net/browse/HHH-16492#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16492#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!

This way, we can have a starting point to reproduce and understand the issue and it makes it much easier to fix. You can start from our test case templates ( https://github.com/hibernate/hibernate-test-case-templates ).
